RELATED APPLICATION

This application claims priority to U.S. Provisional Application No. 62/327,394 entitled SYSTEM AND METHOD FOR DECOMPOSING SOFTWARE COMPONENT INTO STANDALONE FUNCTIONS and filed on Apr. 25, 2016, and U.S. Provisional Application No. 62/327,390 entitled SYSTEM AND METHOD FOR TRANSFORMING A DECISION MANAGEMENT NOTATION GRAPH INTO A FUNCTIONING DISTRIBUTED PROCESS and filed on Apr. 25, 2016, the disclosures of which are incorporated herein by reference in their entirety.

TECHNICAL FIELD

The subject matter described herein relates generally to portable applications and more specifically to techniques for packaging decision logic into software containers.

BACKGROUND

The development of analytic decision applications tends to a time and resource intensive endeavor. An analytic decision application is typically developed by analytic scientists in a familiar language that is optimized for mathematical modeling. Thereafter, the application is rewritten in an enterprise language (e.g., JAVA) in order to integrate with outside security systems as well as to enable monitoring, reporting, and data access. In addition, the application must be configured for deployment and integration with pre-existing information technology (IT) infrastructure. This conventional development process restricts the application to a specific deployment environment while deployment to a different environment will require a repeat of the entire process. After full deployment and running of the application, captured operational and decision metrics, which allow for improvement of the application, have to be manually propagated back to the analytic scientists that originally developed the technology. As such, conventional analytic decision applications lack cross-platform compatibility and are therefore prone to vendor lock-in. Furthermore, data that is generated by conventional analytic decision applications must be transferred back separately.

SUMMARY

The method can include: collecting one or more functions that implement a decision logic of a solution; generating a snapshot of the one or more functions, the snapshot comprising executable code associated with the one or more functions; and deploying the solution by at least storing the snapshot of the one or more functions to a repository. The stored snapshot can be deployed into multiple independent execution environment such as, for example, Spark™, Amazon® Web Services (AWS) Lambda, mobile devices, Internet of Things (IoT) devices, and/or embedded devices.

DETAILED DESCRIPTION

A solution can provide the data model and decision logic for implementing an automated decision process in which an output value is generated based on one or more input values. In particular, the decision logic can specify one or more knowledge models for formulating the output value including, for example, predictive models, optimization algorithms, rulesets, decision trees, decisions tables, scorecards, decision graphs, and/or the like. However, conventional solutions are not configured for nimble deployment across different computing infrastructures such as, for example, distributed computing systems (e.g., Spark™ clusters), serverless computing platforms (e.g., Amazon® Web Services (AWS) Lambda), mobile devices (e.g., smartphones), physical embedded devices (Internet of Things), and/or the like. As such, in some implementations of the current subject matter, a decision management platform can support the definition, deployment, and management of one or more solutions including the accompanying knowledge models. Furthermore, the decision management platform can be configured to provide the solutions as one or more self-contained functions that can be deployed and executed in any runtime, regardless of the underlying computing infrastructure.

In some implementations of the current subject matter, the decision management platform can support the development of a solution by providing a corresponding graphical representation (e.g., Decision Model and Notation™ (DMN™)). For example, the decision logic of a solution can be represented by a directed acyclic graph having a plurality of nodes. Developing the solution can include modifying (e.g., adding, removing, and/or the like) the nodes and/or the edges connecting the nodes. Each node in the directed acyclic graph can correspond to a component that is configured to provide a user interface for configuring that component. For instance, a component can be associated with a knowledge model that can be defined and/or customized during the development of the solution. Furthermore, the component can be configured to host one or more corresponding functions such as, for example, a function implementing the knowledge model, a function providing a mechanism for fetching or saving data, and/or the like. Having a component host enables these functions to be deployed and executed in any runtime as part of a software container. As used herein, component and software container can be used interchangeably. It should be appreciated that a component or a software container (e.g., Docker on Linux or Windows, Oracle® Solaris Zone, and/or the like) can encapsulate the program code for the functions in a complete filesystem for running these functions. The complete filesystem can include, for example, the supporting dependencies and/or artifacts required to execute the functions. An artifact can refer to any tangible byproduct that is produced during the development of a function.

In some implementations of the current subject matter, the decision management platform can support the deployment of a solution to any runtime regardless of the underlying computing infrastructure. The solution can be deployed by publishing a snapshot of the solution, which can include a versioned collection of the components of the solution. This snapshot can be stored at a remote repository, such as Amazon® Simple Storage Service (S3), and/or a lock repository (e.g., a zip file on the local disk), from which the solution can be deployed to one or more runtimes. For instance, the solution can be deployed to a distributed computing system (e.g., a Spark® cluster) as a batch job configured to process a batch of input values. Alternately and/or additionally, the solution can be deployed as a web service hosted by a serverless platform (e.g., Amazon® Web Services Lambda) and/or as a mobile application on a mobile device.

In some implementations of the current subject matter, the decision management platform can control a snapshot over various stages of its lifecycle, which can include creation, submission, approval, and deployment. The lifecycle of the snapshot can be configured to be compliant with one or more regulatory schemes (e.g., Sarbanes Oxley). For example, one user can create a snapshot and subsequently submit the snapshot for approval. One or more other users can review the snapshot to ensure compliance before approving the snapshot. Once approved, the snapshot can be deployed into production in different runtimes such as, for example, a Spark cluster, Amazon® AWS Lambda, a mobile device, and/or an Internet of Things device. It should be appreciated that the stages of the lifecycle of a snapshot can be configured in any appropriate and/or desired manner. For instance, where there are no applicable regulatory schemes, the same user can create, submit, approve, and deploy a snapshot.

FIG. 1 depicts a system diagram illustrating a decision management system 100 consistent with implementations of the current subject matter. Referring to FIG. 1 , the decision management system 100) can include a decision management platform 110. In some implementations of the current subject matter, the decision management platform 110 can be a Platform-as-a-Service (PaaS) that is deployable in a public and/or a public cloud setting. As shown in FIG. 1 , the decision management platform 110 can be communicatively coupled, via a wired and/or wireless network 120, with a client 130 and a repository 140. The client 120 can be device that includes at least one processor and at least one memory including program code such as, for example, a computer, a tablet, a mobile device, a smart phone, and/or the like. The network 120 can be the Internet, a public land mobile network, a wireless local area network (WLAN), a wide area network (WAN), a point-to-point link, and/or the like.

In some implementations of the current subject matter, the decision management platform 110 can support the development of a solution by a user at the client 130. The decision management platform 110 can provide, to the client 130, a user interface 135 that is configured to display a graphical representation of the solution. As noted earlier, the graphical representation of the solution can be a directed acyclic graph having a plurality of nodes. The user can define the solution by interacting with the user interface 135 to modify (e.g., adding, removing, and/or the like) the nodes and/or the edges connecting the nodes.

FIG. 2A depicts a graphical representation 200 of a solution consistent with implementations of the current subject matter. The graphical representation 200 can be a directed acyclic graph that is rendered in accordance with Decision Model and Notation™ (DMN™) and/or any other applicable standard. As shown in FIG. 2A, the graphical representation 200 of the solution can include a plurality of nodes that correspond to various elements of the decision logic underlying the solution. For instance, the graphical representation 200) can include nodes that correspond to a first input 212, a second input 214, a first decision 222, a second decision 224, a knowledge model 230, and a source 240. Furthermore, the plurality of nodes may be connected via edges indicating the dependencies between the various elements of the decision logic.

Referring to FIG. 2A, the directed edges from the first input 212 and the second input 214 to the first decision 222 can indicate that the first decision 222 requires both the first input 212 and the second input 214. Meanwhile, the directed edge from the first decision 222 to the second decision 224 can indicate that the second decision 224 requires output from the first decision 222. The directed edge from the knowledge model 230 to the first decision 222 indicates that the output of the first decision 222 can be formulated by applying the knowledge model 230 to the first input 212 and/or the second input 214. As noted earlier, the knowledge model 230 can include one or more predictive models, optimization algorithms, business and operational rules, decision trees, decisions tables, scorecards, decision graphs, and/or the like. Alternately and/or additionally, the edge between the source 240 and the knowledge model 230 can indicate that the source 240 is responsible for defining and/or maintaining the knowledge model 230.

To further illustrate, the graphical representation 200 can depict the decision logic for a solution for processing credit card transactions. The second decision 224 can be a decision to approve and/or deny a pending credit card transaction while the first decision 222 can be a decision on a risk of fraud associated with the pending credit card transaction. In accordance with the graphical representation 200, the decision to approve and/or deny a pending credit card transaction can require the output from the decision on the risk of fraud associated with the pending credit card transaction. For example, the pending credit card transaction may be denied in instances where the risk of fraud exceeds a threshold value. Meanwhile, the decision on the risk of fraud associated with the pending credit card transaction can require the first input 212 and the second input 214. The first input 212 can be customer information while the second input 214 can be transaction information. Furthermore, the decision on the risk of fraud associated with the pending credit card transaction can be made by applying the knowledge model 230 to the customer information and/or the transaction information. For example, the knowledge model 230 can be a decision tree that determines the risk of fraud associated with the pending credit card transaction based on a geographic location of the customer and/or the amount of the transaction. It should be appreciated that the solution can be defined by modifying one or more of the first input 212, the second input 214, the first decision 222, the second decision 224, the knowledge model 230, and/or the source 240. The modification can include customizing the knowledge model 230 to include a customized predictive model, optimization algorithm, ruleset, decision tree, decisions table, scorecard, decision graph, and/or the like.

In some implementations of the current subject matter, the decision management platform 110 can support the deployment of a solution by the client 130. For example, by interacting with the user interface 135, the client 130 can deploy the solution to any runtime, such as a first endpoint 150A and/or a second endpoint 150B, regardless of the underlying computing infrastructure. The decision management platform 110 can support the deployment of the solution to any runtime (e.g., the first endpoint 150A and/or the second endpoint 150B) by generating one or more components implementing the solution. Specifically, the decision management platform 110 can generate at least one function for each input node, decision node, and/or knowledge model node in the graphical representation of the solution. The functions associated with a node can be hosted by a corresponding component, which serves as a software container encapsulating the functions as well as the supporting dependencies and/or artifacts required to execute the functions.

According to some implementations of the current subject matter, a component that hosts one or more functions can be generated based on a corresponding component archetype. As used herein, a component archetype can be a template that includes the resources for instantiating a specific type of component. These resources can include, for example, a descriptor file (e.g., component.json), implementation artifacts (e.g., a Java WAR file), and/or documentation (e.g., a license file). The descriptor file can indicate the types of functions that are supported by the corresponding component. Specifically, the component archetype may include one or more function factories that are each configured to generate a specific type of function.

Each component can provide a standard interface (e.g., a function factory) that is capable of generating a specific type of function. In some implementations of the current subject matter, the decision management platform 110 can call the function factory with a request to provision a specific type of functions at a specific Web Service Path. The function factory can respond to the request by fulfilling the request from the decision management platform 110 and generate the specific type of function at the specific Web Service Path. Here, the function factory can generate the specific function and return, for example, the universal resource locator (URL) of the function. The decision management platform 110 as well as applications that use the decision management platform 110 can use the universal resource locator of the function to directly configure the function. Alternately and/or additionally, the function factory can respond to the request by indicating to the decision management platform 110 that the function factory cannot fulfill the request. In this latter case, the decision management platform 110 can create another component to generate and host that function.

Table 1 below depicts an example of a descriptor file that can be used by the decision management platform 110 to generate a specific type of function.

TABLE 1 {   “kind” : “component”,  “contributions” : [ { “id” : “<factory id>”, “kind” : “factory”, “type” : “function”, “name” : “<readable function type name>”, “description” : “<function type description>”, “version” : “<SemVer-compatible version of module type, e.g. 1.0.0>”, “url”:“/functions”, “keywords” : [ “<keyword 1>”, “<keyword 2>” ], “icons” : [ {  “url” : “<icon URL, e.g. public/img/icon64x64.png>”,  “size” : “64x64”,  “active” : true }] “multipleArgs” : false, “interfaces” : [ “com.fico.dmp.functions.BusinessKnowledgeModel”,  “com.fico.dmp.functions.DMPBoxcaringFunction” ],  “contributions”: [  {  “kind” : “event”,  “name” : “user-friendly event type name”,  “description” : “_”,  “type”: “Java class name or reference to a type declared in a schema  provided in the component.json itself”,  “id”: “event id/key under which this event will be inserted into  DMPEntity's event map”  }, {“kind”: “event”, ...} ] }], }

It should be appreciated that an instance of a component that is generated based on a corresponding descriptor file can also have a descriptor file having the same and/or similar descriptor. However, the active flag in the factory contribution of this descriptor file may be set to false in order to indicate that no additional functions can be generated by this function factory. The decision management platform 110 can generate functions across multiple components based on the presence of active flags. Meanwhile, the multipleArgs flag can indicate if the function factory generates a function that intakes a single argument or multiple arguments. The contribution attribute can describe an optional set of event types that trigger the logging of event data by the function generated by the function factor.

As noted earlier, each function factory of a component is configured to generate a specific type of function. For example, a function factory can be configured to generate a function that implements a knowledge model, such as the knowledge model 230. A different function factory can be configured to generate a function that injects one or more data models. Alternately and/or additionally, a function factory can be configured to generate a binding function that maps and/or transforms between the output and inputs of various functions in a solution.

Referring again to FIG. 2A, the decision management platform 110 can support the deployment of the solution associated with the graphical representation 200. As such, the decision management platform 110 can generate one or more functions implementing the first input 212, the second input 214, the first decision 222, the second decision 224, and/or the knowledge model 230. For example, the decision management platform 110 can identify, based on the corresponding descriptor files, the component archetype that can be used to generate the function for implementing the knowledge model 230. The decision management platform 110 can generate an instance of the component to host the function for implementing the knowledge model 230. Furthermore, the decision management platform 110 can further call the resulting instance of the component to add, to the component, the decision tree underlying the knowledge model 230. The resulting component can then be deployed to any runtime and be executed as part of the running the solution associated with the graphical representation 200.

As noted earlier, a component can serve as a software container that encapsulates one or more functions as wells the supporting dependencies and/or artifacts required to execute the functions. Thus, generating a function and the corresponding component that host the function can encapsulate the function as part of software containers. In doing so, the decision management platform 110 is able to deploy the solution associated with the graphical representation 200 in any runtime, regardless of the underlying computing infrastructure. In some implementations of the current subject matter, the decision management platform 110 can also inject, into the component hosting one or more functions, additional services required for executing the functions in any runtime. For instance, the decision management platform 110 can inject security filters that ensure only authorized users are given access to a component and its constituent functions. The decision management platform 110 can further inject file data filters that ensure compliance with legal and/or organizational guidelines.

FIG. 2B depicts a block diagram illustrating a component 250 consistent with implementations of the current subject matter. The decision management platform 110 can generate the component 250 in order to host one or more functions such as, for example, functions that implement any one of the first input 212, the second input 214, the first decision 222, the second decision 224, and the knowledge model 230. As shown in FIG. 2B, the component 250 can include metadata such as, for example, a component identifier, a component description, licenses, links to documentation, and/or the like. The component 250 can further include dependencies, input data, engine (e.g., Tomcat, JBOSS, and/or the like), services (e.g., Hadoop® Distributed File System, Couchbase, MySQL, and/or the like), contributions, output data, configuration endpoints, knowledge models, execution endpoints for decision invocation (e.g., Simple Object Access Protocol (SOAP) and/or Representational State Transfer (REST) endpoints), and functions. As used herein, functions may be smaller executional code (e.g., Java Archive (JAR)) that is able to execute a decision outside of a software container.

In some implementations of the current subject matter, the decision management platform 110 can deploy a solution by storing a snapshot of the solution to the repository 140. For instance, a user can publish the solution by at least interacting with the user interface 135 at the client 130. In response to the publishing of the solution, the decision management platform 110 can collect all of the functions that are exposed by the components generated for the solution and the corresponding artifacts. As noted earlier, the functions can be generated by corresponding function factories, which are configured to return the universal resource locator of the functions. As such, functions can be collected via a Hypertext Transfer Protocol (HTTP) REST call to the universal resource locator of each individual function. Calling the universal resource locator of a function can return the executable code for the function as well as the artifacts associated with the function. These artifacts can be captured, validated for correctness, and cached locally. Once all of the functions have been collected, the decision management platform 110 can upload the functions to a repository with a special solution descriptor (e.g., solution.js) that defines the snapshot in its entirety. Each individual function can be placed in a directory under the function snapshot, where the directory name corresponds to the identifier of the function returned by the function factory that generated the function. It should be appreciated that the functions can be linked via orchestrations such as, for example, Decision Model and Notation™ service definition and/or the like. Furthermore, the decision management platform 110 can also contribute its own function for managing the orchestration and execution of different functions.

The decision management platform 110 can further store the functions and the artifacts as a snapshot into the repository 140. According to some implementations of the current subject matter, the decision management platform 110 can store the snapshot to a location within the repository 140 (e.g., an AWS S3 bucket) that is specifically provisioned for the snapshot. That location within the repository 140 can serve as a deployment package 145 that enables the solution to be deployed to one or more runtimes including, for example, the first endpoint 150A and/or the second endpoint 150B. For example, a batch job that applies the solution to a batch of input values can be scheduled with the snapshot contained within the deployment package 145 as the definition of the batch job to be performed. Alternately and/or additionally, the deployment package 145 can also be made available over the network 120 such that the solution can be accessed as a web service.

FIG. 3 depicts a block diagram illustrating the decision management platform 110 consistent with implementations of the current subject matter. Referring to FIGS. 1 and 3 , the decision management platform 110 can include a plurality of components including, for example, a solution builder 310, a function generator 312, a deployment engine 314, and a user interface 316.

In some implementations of the current subject matter, the solution builder 310 can be configured to support the development of a solution. For instance, the user of the client 130 can interact with the user interface 135 to develop a solution for processing credit card transactions. The solution can be developed based on a corresponding graphical representation, such as the graphical representation 200, which the solution builder 310 can provide to the client 130 via the user interface 135. It should be appreciated that the solution builder 310 can support any type of standard for graphically representing the solution including, for example, Decision Model and Notation™ (DMN™) and/or the like.

As noted earlier, the user can develop the solution by modifying the graphical representation of the solution including by modifying the nodes in the graphical representation and/or the edges connecting the nodes. Referring again to FIG. 2A, the user can generate the graphical representation 200, which can graphically portray the decision logic underlying the solution for processing credit card transactions. The nodes for the first input 212, the second input 214, the first decision 222, the second decision 224, the knowledge model 230, and the source 240 indicate the elements that are present in the decision logic. Meanwhile, the edges between the nodes can indicate the dependencies between two or more elements. For example, the second decision 224 can require the output from the first decision 222 which in turn requires applying the knowledge model 230 to both the first input 212 and the second input 214.

The function generator 312 can be configured to generate one or more functions for each of the nodes in the graphical representation of the solution. The generating of a function can include generating a component that is configured to host that type of function. For example, the function generator 312 can be configured to identify a component archetype for generating a component that can host the type of function. The identification of the component archetype can be performed based on the descriptor file (e.g., component.json) included in the component archetype. It should be appreciated that the function generator 312 can determine, based on the descriptor file, that the component archetype include a function factory that is configured to generate this specific type of function. The function generator 312 can subsequently generate, based on the component archetype, an instance of the component. Furthermore, the function generator 312 can invoke the function factory to generate the function. The resulting function can be added to the component, which serves as a software container for the function that enables the function to be deployed in any runtime. As noted earlier, the component can provide the complete filesystem required for running the function including, for example, the supporting dependencies and/or artifacts required to execute the functions.

The deployment engine 314 can be configured to deploy a solution to any runtime, regardless of the underlying computing infrastructure. For example, the deployment engine 314 can deploy the solution to a distributed computing system (e.g., a Spark® cluster) as a batch job configured to process a batch of input values. Alternately and/or additionally, deployment engine 314 can deploy the solution as a web service hosted by a serverless platform (e.g., Amazon® Web Services Lambda) and/or as a mobile application running on a mobile device.

In some implementations of the current subject matter, the deployment engine 314 can be configured to deploy a solution that has been published by the user via the user interface 135 on the client 130. The publishing the solution can prompt the deployment engine 314 to collect the functions and the artifacts associated with the solution, both of which can be exposed by the components that the function generator 312 had generated earlier. The deployment engine 312 can further deploy the solution by storing the functions and the artifacts as a snapshot into a repository, such as the repository 140. In particular, the deployment engine 312 can store the snapshot at a specific location within the repository 140 (e.g., an Amazon® Simple Storage Service (S3) bucket) that can serve as the deployment package 145 for the solution. As such, the solution can be deployed using the deployment package 145. For example, a batch job executing the solution to process a batch of input values can be scheduled with the deployment package 145 as the definition of the batch job to be performed. Alternately and/or additionally, the deployment package 145 can also be made available over the network 120 such that the solution can be accessed as a web service.

Deployment of the deployment package 145 to a runtime environment can trigger the start of a local executor that is specific to that particular runtime environment. For example, a Spark cluster can have a SparkExecutor while Amazon® AWS Lambda can have a LambdaExecutor. This local executor can use a library called FunctionExecutor to complete the deployment of the deployment package 145. Specifically, the FunctionExecutor can be configured to download the contents of the solution snapshot, the artifacts and implementation of each function, the descriptors for the overall function, and/or the like. The FunctionExecutor can further validate the individual configurations for each function. Furthermore, the FunctionExecutor can identify orchestration artifacts (e.g., provided by Decision Model and Notation™) and translate the orchestration artifacts (e.g., the Decision Model and Notation™ graph) into a suitable local representation using a depth-first traversal of the structure. The FunctionExecutor can insert appropriate transformation steps at various points. For instance, the FunctionExecutor can insert transformation steps for serializing and/or de-serializing input data from a third party data source. The FunctionExecutor can further execute the combined structure according to the requirements of the local executor. In Spark, for example, the FunctionExecutor can translate the graph into a structured DataFrame, DataSet, and/or Resilient Distributed Dataset (RDD) such that the contents of the deployment package 145 can be executed in a streaming and/or a batch context. By contrast, in Lambda, the FunctionExecutor can translate the graph into a tree containing different direct Java calls. This tree can be fed via streaming (e.g., Amazon® Kinesis) and/or web requests via an application programming interface (API) gateway.

In some implementations of the current subject matter, the deployment package 145 can be deployed to mobile device as a .zip file. For example, some mobile devices can be subject to manufacture restrictions that prevent the dynamic downloading of new content. As such, the deployment package 145 can be made available to the mobile device as a local zip file containing the complete repository.

The user interface 316 can be configured to provide one or more user interfaces, such as the user interface 135, which can be used to interact with the decision management platform 110. For example, the user interface 316 can generate the user interface 135 to enable the user of the client 130 to develop a solution. As such, the user interface 135 can display a graphical representation of the solution, such as the graphical representation 200 shown in FIG. 2A. The user interface 135 can further enable the user to modify the graphical representation of the solution by adding and/or removing the nodes in the graphical representation and/or the edges connecting the nodes. Alternately and/or additionally, the user interface 316 can generate the user interface 135 to enable the user of the client 130 to publish and/or deploy the solution. For instance, publishing the solution can prompt the decision management platform 110 to store a snapshot capturing the functions and/or artifacts forming the solution to the repository 140 as the deployment package 145. The solution can further be deployed from the repository 140 as a batch job, a web service, and/or a mobile application running on a mobile device.

FIG. 4A depicts a flowchart illustrating a process 400 for developing a solution consistent with implementations of the current subject matter. Referring to FIGS. 1-3 and 4A, the process 400 may be performed by the decision management platform 110.

The decision management platform 110 can generate a graphical representation of a decision logic underlying a solution (402). For example, the decision management platform 110 (e.g., the solution builder 310) can enable the user of the client 130 to develop a solution by modifying a graphical representation of the solution. Modifying the graphical representation of the solution can include adding and/or removing nodes and/or edges from the graphical representation. Alternately and/or additionally, modifying the graphical representation of the solution can include customizing an underlying knowledge model to include a customized predictive model, optimization algorithm, ruleset, decision tree, decisions table, scorecard, decision graph, and/or the like. It should be appreciated that the resulting graphical representation of the solution, such as the graphical representation 200, can set forth the decision logic underlying the solution. The graphical representation of the solution can include nodes that correspond to various elements of the decision logic including, for example, inputs, decisions, knowledge models, sources, and/or the like. Furthermore, the graphical representation of the solution can include edges that indicate the dependencies between the various elements of the decision logic.

The decision management platform 110 can identify a component archetype that supports the generation of at least one function implementing a node in the graphical representation of the solution (404). The component archetype of a component can include a descriptor file (e.g., component.json) that indicates the types of functions that are supported by the corresponding component, which is an instance of the component generated based on the component archetype. Specifically, the component archetype can include function factories that can be used to generate specific types of functions. As such, in some implementations of the current subject matter, the decision management platform 110 (e.g., the function generator 312) can identify, based on the descriptor file in each available component archetype, the appropriate component archetype. For example, the decision management platform 110 can identify, based on the descriptor file in each available component archetype, a component that supports generating a function implementing the knowledge model 230.

The decision management platform 110 can generate an instance of the component based at least on the component archetype (406). For example, the decision management platform 110 can generate, based on the component archetype, an instance of the component that supports the generation of the function implementing the knowledge model 230.

The decision management platform 110 can invoke the instance of the component to generate the at least one function (408). For example, the decision management platform 110 can invoke the instance of the component, specifically the function factory, to generate the function implementing the knowledge model 230. In doing so, the instance of the component can host the function implementing the knowledge model 230. That is, the component can provide the program code associated with the function as well as the complete filesystem required for executing the function including, for example, the supporting dependencies and/or artifacts required to execute the functions. As noted earlier, the component can serve as a software container for the function, thereby enabling the function to be deployed in any runtime regardless of the underlying computing infrastructure (e.g., distributed computing system, serverless platform, mobile device, and/or the like).

FIG. 4B depicts a flowchart illustrating a process 450 for deploying a solution consistent with implementations of the current subject matter. Referring to FIGS. 1-3 and 4B, the process 400 can be performed by the decision management platform 110.

The decision management platform 110 can respond to the publication of a solution by at least collecting the functions and the artifacts associated with the solution to generate a snapshot of the solution (452). For example, the user of the client 130 can publish a solution by interacting with the user interface 135. The publication of the solution can prompt the decision management platform 110 (e.g., the deployment engine 314) to collect all of the functions and artifacts associated with the solution, which can be exposed by the host components. These functions and artifacts can form a snapshot of the solution.

The decision management system 110 can deploy the solution by at least storing the snapshot of the solution at a repository (454). In some implementations of the current subject matter, the decision management platform 110 (e.g., the deployment engine 314) can deploy the solution by storing a snapshot of the solution (e.g., its constituent functions and artifacts) to the repository 140. The decision management platform 110 can store the snapshot at a specific location within the repository 140 (e.g., an Amazon® Simple Storage Service (S3) bucket) that has been provisioned for storing the snapshot. This location can serve as a deployment package, such as the deployment package 145, for the solution. For example, a batch job executing the solution to process a batch of input values can be scheduled with the deployment package 145 as the definition of the batch job to be performed. Alternately and/or additionally, the deployment package 145 can also be made available over the network 120 such that the solution can be accessed as a web service.
